- Summary
- CVE-2025-68229 affecting package kernel for versions less than 6.6.119.3-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: tcmloop: Fix segfault in tcmlooptpgaddress_show()
If the allocation of tlhba->sh fails in tcmloopdriverprobe() and we attempt to dereference it in tcmlooptpgaddressshow() we will get a segfault, see below for an example. So, check tl_hba->sh before dereferencing it.
